The Better Business Bureau received the most complaints from consumers about cell-phone poviders and cable/satellite TV provides in 2009. These two industries accounted for a total of 70,093 complaints, with cable/satellite TV providers receiving 4861 fewer complaints than cell-phone providers (Source: Better Business Bureau). How many complaints did each industry receive?

Answer 1

Total of 70,093 complaints, cable/satellite TVproviders receive 4861 fewer complaints than cell-phone providers.
Let the number of cable/satelliteTV providers complaints is x, then the number of cell-phoneproviders complaints is (x + 4861).
So, to find how many complaints did each industry receive, we shouldcreate the next equity:
x + (x + 4861) = 70093
2x = 65232
x = 32616, so cable/satellite TV providers made 32616 complaints in2009.
Cell-phoneproviders made32616 + 4861 = 37477 complaints in 2009.
